METHOD OF PRODUCING IMPROVED COLOR EFFECTS IN TWO-PLY INGRAIN CARPETS.

SPECIFICATION forming part of Letters Patent No. 371,571, dated October 18, 1887.

(Spewimena) To all whom, it may concern.-

Be it known that I, James L. FoLsoM, of Brooklyn, New York, haveinvented a certain new and useful Method for Producing Improved Color Effects in Two-Ply Ingrain Carpeting, of which the following is aful], clear, and exact description, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

My invention relates to a method of weaving two ply ingrain carpets, by which the filling-threads of the two plies are so disposed and arranged as to produce improved and novel color effects and designs.

Hitherto in weaving-two ply ingrain carpets, where there were two or more different- ]y-colored filling-threads in a ply, the threads of that ply have been shot successively with respect to each other-that is, a thread of one color, then a thread of the second color, then a thread of the third color, and so on until a thread of each color had been shot, and then the same order would be repeated. For example, in weaving the most common form of two-ply ingrnin carpets-namely, that having two filling-threads of different colors in eachply-a thread of one ply was thrown, then a thread of the other ply, then thesecond thread 0 of the first ply, amt-lastly, the remaining thread of the second ply, and then this succession of threads was repeated. Thus the order and arrangement of the colors upon the surface of the carpet were necessarilylimited. In my improved method I employ two filling-threads in the figure ply and three fillingthreads in the ground ply. These fillingthreads I throw in a regular but novel succession. For example, if the two threads of the figure ply are red and black, Ithrow them in the following order: red, black, blacl ,black, red, black, black, black, and so on, throwing the second filling-thread three times to each single throw of the first filling'thread. If the 5 three filling-threads of the ground ply are white, cinnamon, and blue, I throw them in a definite order-as, for example, white, cinnamon, blue, cinnamon, white, cinnamon, blue, cinnamon, and so on. As the loom throws a shot in each ply alternately, the actual order of the filling-shots in the weaving of the carpetwould be as follows; red, white, black, einnamon, black, blue, black, ciunamon,red,white, black, cinnamon, black, blue, black, cinnamon, and so on, the colors in italics representing the threads of one ply and those notin italics the threads of the other ply. Figure l is a diagram representing a longitudinal section of the carpet woven in this manner, so far as to show the relative positions of the different filling-threads, it being assumed, for the sake of greater clearness, that all the threads of the figure ply are up and all the threads of the ground ply are down. In this diagram 1 is a section of ared filling thread; 2, white; 3, black; 4, cinnamon; 5, black; 6, blue; 7,blacl 8, cinnamon; 9, red; 10, white; 11, black; 12, cinnamon; 13, black; 14, blue; 15, black; 16, cinnamon. This arrangement would be re peated.

By means ofthejacquard the thread ofcithcr ply can be thrown up to the top of the carpet, the corresponding thread of the other ply being ordinarily thrown down to the bottom at that point ofthe fabric. The filling-threads employed in the two plies may of couise be of any colors desired so long as three colors are employed in one ply and two colors in the other ply; but the filling-threads must be shot and woven into the carpet in a defined sucees- 8o sion, as is indicated above. The particular succession or arrangement oft-he filling-threads on the surface of the carpet will be greatly varied by the operation of thejacquard, which can be made to throw the threads of either 8; ply to the top of the fabric at any point, as desired.

The characteristic feature of my invention lies in the employment of the different numbers of filling-threads in the two plies-two in one ply and three in the other ply-and in the special order of succession of those threads viz., in one ply one shot ofonc thread, followed by three shots of the other thread, and in the other ply one shot of each thread at a time, the threads succeeding each other in any dofined order. As a result of my improved process, I produce novel and superior color ef fects on the face of two-ply ingrain carpets different from anything hitherto produced.

My invention may be carried out in any pets by providing the "proper number ofshuttles and shuttle-boxes both, for the forward and rear shuttle frames of the loom and mechanism to bring those shuttle-boxes'in proper succession into operative position for their shuttles to beacted upon by the pickersticks. For instance, Figs. 2 and 3 show the changes which it is necessary to make in a two-ply ingrain loo'm in which the path of motion of the picker-stick on eithersideoftheloom is always the same and the shuttleframe is moved so as to bring the shuttles, when desired, within the range of motion of the picker-stick. Fig. 2 is a side view of the rear shuttle-frame of such aloom on one side of the loom and of its operating and controlling mechanism, and Fig. 3 is a similar view of the front shuttleframe. In both of these figures G is the shuttle-box frame and supporting-rod. O is a lever fulcrumed in the frame of the loom at E, and carrying the shuttle-box frame G atits end F, where it is pivoted to such frame, and held down at its end L by the strong spring M, secured to a part of the loom-frame N. This lever O is held down at its end L, so

that the roller D, mounted on it, is kept always in contact with the cam B in the one case and with the cam B in the other case, which are mounted on the cam shaftA of the loom. These two shuttle-regulating mechanisms represented in Figs. 2 and 3 are distinct from each other in the loom, excepting that the cams B and B are both mounted on the same camshaft, A, and the two shuttlebox frames G (to wit, the front and rear shuttle-box frames) are adapted in any well-known way to be alternately presented to the pick er-stick, whose position is indicated at P in both figures.

In Fig. 2, S and R are the two rearshuttleboXes, adapted to receive shuttles carrying, respectively, say, black and red yarn, S in the In Fig. 3, H, J, and K are the three shuttleboxes adapted to receive shuttles carrying, say, blue, cinnamon, and white, respectively, H in the instance assumed above receiving a shuttle carrying blue yarn, J a shuttle carrying cinnamon yarn, and K a shuttle carrying white yarn. The shape of the cam as shown in Fig. 3 presents the shuttle-boxes H, J, and K in a definite succession-t0 wit, H J K J H J K, &c.-to the picker-stick at P, and

. thereby determines the order of succession of the shots of filling-thread in the ply under considerationm wit, the ground ply.

I do not herein claim the mechanism herein described, nor do I restrict myself to any particular mechanism.

What I claim as new, and desire to secure by Letters Patent, is-- The method, substantially as described, of

producing improved color effects in two-ply ingrain carpets, which consists in employing two distinct and differently colored or shaded filling-yarns for one ply, throwing such fillingyarns in such ply in the definite order or succession of one throw of one yarn and three throws of the other yarn, and employing three distinct and differently colored or shaded filling-yarns for the other ply, and throwing such. filling-yarns in such second ply in any definite order or succession.
